ZSE 12 HP-PH: the smallest Leistritz twin screw!

Leistritz Extrusionstechnik GmbH will be presenting at the Interpack Fair their range of

products and services from the pharmaceutical and direct extrusion sectors. The smallest

twin screw extruder must not be missed here: the ZSE 12 HP-PH in GMP design for phar-

maceutical applications.

Düsseldorf (May 4, 2017) – „This twin screw extruder is the smallest machine Leistritz has

ever built,“ says Albrecht Huber, Head of Pharma Extrusion at German Leistritz Extrusion-

stechnik GmbH. “We will be presenting the concept of our smallest extruder which is

applied in the pharmaceutical industry.“ On each of the seven fair days, there will also be

an Info Hour at 5 pm giving an “Insight into Extrusion Technology 4.0”. „Our aim is to

provide our customers an added value. This definitely includes some of the features deal-

ing with Industry 4.0. We will show that in our lectures with a few examples,” says Huber.

Those examples involve efficient service via iGlasses, the advantages of an online

rheometer used in both R&D and production. In addition, visitors will see how the

process can be analyzed by means of UV light.

ZSE 12 HP-PH

The ZSE 12 HP-PH realizes a throughput of 50 to 1,000 g/h and is therefore ideal for

research and development. The production of clinical batches is also possible with this

machine, depending on the requirements. During the design phase of the ZSE 12 HP-PH

special attention was given to easy handling, simple assembly and disassembly, as well as

good cleanability. The machine has a mobile design and horizontally split barrels which

facilitate a look at the process. The screws are only available in compact layout in order

to reach maximum torques. „The heating/cooling system was a very important issue for

us,“ says Albrecht Huber. “We invented an innovative concept which has not been avail-

able in the pharmaceutical market until now.” It facilitates the control of eight separate

heating and cooling zones, and it also has temperature probes. The heating/cooling de-

vice can easily be assembled and disassembled due to a simple clamping system. “A fur-

ther highlight is the powerful drive,” explains Albrecht Huber. The high torque of 20 Nm

ensures stable operation at various process conditions and scale-up to the larger next

machine size. After all, the geometrical characteristics of the ZSE 12 HP-PH comply with

the larger ZSE HP-PH machines. All this is rounded off by a PLC control with a large touch

screen that controls and monitors all necessary extruder functions like torque setting and

heating/cooling.
